Pb woth RFC communication

Hi PI Expert,

I'm working on a ECC6 RFC Sender -> PI -> Web service Receiver Scenario.

My RFC connexion TCP/IP (type T) on ECC6...:

-worked fine yesterday (test connexion function => OK)

-doesn't work anymore today (test connexion function =>Time out error message)

I don't see anything strange in SM58 nor SMGW....

some tips : yesterday, i stopped tests in the evening after waiting and waiting SE38 execution results on ECC6. And i had to kill with SMGW actives connexions in "Interrupting..." status...

Thanks a lot for your help

Regards

Etienne
